PEF (polyethylene furanedicarboxylate) is a 100% biomass sourced all-bio-based polyester material made from the condensation polymerization of the biobased platform compound FDCA (2, 5-furanedicarboxylic acid) with ethylene glycol. It is recognized as the next generation's most promising petroleum-based pet (polyethylene terephthalate) replacement material. Conventional forms are high-transparency flakes, films or fibers. With its unique furan ring molecular structure,

PEF comprehensively surpasses traditional pet in barrier properties, mechanical strength and thermal properties, is widely used in food and beverage packaging, textile fibers, electronic insulation materials and new energy energy storage, and can be further applied to carbonated beverage bottles, beer bottles, food preservation films, antibacterial textiles and film capacitors.
